To all whom it may concern:

Be it known that I, JOSEPH RoLLINs, a citizen of the United States, residing at Birnam-,

wood, in the countyofShawano and State of Wisconsin ,have invented certain new and useful Improvements in Rotary Horizontal Excelsior-Machines and I do declare the following to be a full,'clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. A

My invention relates to improvements in rotary ex'celsior-machines of the'horizontal type; and the object is to improve and simplify the construction and increase the efficiency. and capacity of the machine.

To these ends'the invention consists in the construction, combination, and arrangement of theseveral parts of the device, as will be hereinafter more fully described, and particularly pointed out in the claims.

The accompanying drawings show my invention in the best form now known to me; but many changesin the details might be made within the skill of a good mechanic without departing from the spirit of my i11- vention. v i

The same reference characters indicate the same parts ofth'e invention.

Figure 1- is a top plan view of my improved excelsior-machine. Fig. 2 is atransverse section of the same. Fig. 3 is a detail View of the feed-rollers. Fig. leis a transverse sec tion through the feed rollers. Fig. 51s a side elevation of the feed roller frame. Fig. 6 is a similar viewof the opposite side of said frame.

1 denotes a rectangular frame provided with the vertically-alined bearing-boxes 2 and 3, in which is journaled. the vertical driving-shaft 4, on which is fixed the horizontal driving-pulley 5. v

6 represents a circular rotating table or cutter-head horizontally fixed on the vertical driving-shaft 4 and-which rotates in the direction of the arrow shown in Fig. 1, and it is formed witha series of radial slots 7 and S, arrangedin pairs, which are approximately parallel with each other, as shown. 7

9 denotes the plane-knife or cutter-blade,

adj ustably secured in the slot 7 by means of the set-screws 10 10, and 12denotes the scoring-knife, likewise adj ustably secured in the slot 8 by the set-screws 14 14..

15 represents a horizontal worm-screw fixed on the vertical driving-shaft 4t, and it meshes with a vertical worm-wheel 16, fixed on the inner end of a radial horizontal shaft 17 journaled in the h'angerslS and 19, fixed to the upper horizontal beam, and at its outer end in the bearing box 20, fixed to one of the vertical posts of the frame 1.

21 denotes a longitudinally-corrugated feedroll fixed on said shaft 17, and 22 23 denote parallel plates formed at one end with the slots to receive the stationary bearing-boxes 24 24, which encompass the shaft 17 on the opposite ends of the feed-roller, and at their opposite end with corresponding slots to receive the movable bearing-boxes 25 25, in

' which is journaled a longitudinally-corrugated feed-roller 26, arranged parallel with the feed-roller 21.

21 and 21 denote similar feed-rollers journaled in the boxes 24 and 24*, arranged in the same vertical plane with the roller 24., and 27 represents a spur-gear fixed on the shaft 17, and27 and 27 corresponding spurgears fixed on the feed-rollers 21 and 21*", respectively.

2S and 29denote stud-shafts fixed to the side of the plate 22, and 30 31 spur-gears or idlers loosely journaled on said stud-shafts and which intermesh with the feed-roller gears 27, 27, and 27 and 27?", respectively, whereby motion is given to said feed-rollers 21 21 to simultaneously rotate them in the same direction to feed the bolt to the cutters.

32 denotes a bevel-gear fixed 011 the outer end of the shaft 17, which meshes with a corresponding bevel-gear 33, fixed on the adj oining end of a horizontal shaft 34, journaled in alined bearing boxes 35 35, fixed to the outside of the plate 23, and its opposite end carries a bevel-gear 36,'which meshes with a correspondingbevel-gear 37, fixed on the outer end of the feed-roller 26. The bevelgear 36 is provided with a keyway which engages a key 38 in the shaft 34, and 3 9 denotes a right-angular strap fixed to the contiguous bearing-box 25, with its free end encompassing the shaft 34, so as to retain the gear 36 in mesh irrespective of the parallel adjustment of the feed-roller 26 with reference to the feed-roller 21.

26 26 denote corresponding feed-rollers journaled in boxes 25 and 25 vertically alined and horizontally adjustable in slots in the same ends of the plates 22 23 as the roller 26, and the inner end of this latter roller 26 carries a spur-gear 10, and the same ends of the rollers 26' 26 carry correspondinggears l0 and 40 41 denotes a curved strap, one end of which encompasses the shaft of the roller 26, and its free end is provided with a stud-shaft 42, which receives the outer end of a straight strap 1-3, the inner end of which encompasses the shaft of the roller 26. A curved strap 41' also encompasses the shaft of the roller 26, and its free end carries a stud-shaft 12, from which a straight strap 1-3 extends to the shaft of the roller 26. A spur-gear H is loosely journaled on the stud-shaft 42, so as to mesh with the spur-gear 1-0 on the shaft of the feed-roller 26 and also with a corresponding gear 10 on the shaft of the feed-roller 2 J, and a similar spurgear 4* is journaled on the stud-shaft12, which in turn meshes with the gear 4- and the corresponding gear 4- 1 on the shaft of the feed-roller 26 1-5 and 4-6 denote tension-springs which extend from the free ends of the curved straps 11 and 11 to the stud-shafts 2S and 29, the otlice of which is to automatically adjust the feed-rollers 26, 26', and 26 with reference to the corresponding feed-rollers 21, 21, and 21 while the bolt is being fed between them.

The outer ends of the rollers 21, 21, and 21 are connected by the V-shaped straps 17 and 17 and the similar ends of the rollers 26, 26, and 26 by the correspondingly-formed straps 8 and 18, the straps 17 and *8 being connected by the tension-spring 49 and the straps 17 and 18 by the corresponding spring 19', and the latter springs, together with the springs 45 and 16 first mentioned, serve to equalize the pressure of the feed-rollers on the bolt, and thus insure a regular uniform feed of the bolt to the cutters.

\Vhile I have only described the operation of one set of cutters and feed-rollers, in Fig. 1 I have shown a series of the cutters and two sets of feed-rollers, and of course it will be understood that the number of sets of feedrollers may be increased up to the full capacity of the machine, so that an indefinite number of belts or blocks may be utilized at the same time.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is-

1. The vertical driving-shaft 4., the horizontal rotating cutter-head 01. table 6, fixed to said shaft and the cutters f) and 12, carried by said table and a worm-screw 15 fixed to said shaft, in combination with the horizontal shaft 17, the worm-wheel 16 fixed on the inner end of said shaft, the feed-roller 21 and bevel-gear 32, fixed on the parallel plates 22, 223, encompassing the outer end of said shaft 17, the horizontal shaft 34. journaled in bearings fixed to the plate 2:) and the bevel-gear 33 fixed on one end of said shaft and in mesh with the bevel-gear 32, the bevel -gear 36 longitudinally adjustable on the opposite end of said shaft 34, the spring-actuated feedrollcr journaled in the opposite ends of said plates, the bevel-gear 37 fixed on one end of said feed-roller, and means for holding said gear 36 in mesh with the gear 37, irrespective of its position on its shaft, as and for the purpose set forth.

2. A bolt-feeding device for excelsior-ma chines comprising the parallel plates 22, 23, the feed-rollers 21, 21, 2 journaled in the same vertical plane in the same ends of said plates, and means for simultaneously rotating said feed-rollers in the same direction, the bevel-gear 32 carried by the feed-roller 21, the shaft 31 formed with a longitudinal key at one end and the bevel-gear 3 fixed on the opposite end of said shaft and in mesh with the gear 32, and the bevel-gear 36 longitudinally adjustable on the keyed end of the shaft 8%, the spring-actuated feed-rollers 26, 26' and 26 adjustably mounted in the opposite ends of said plates 22, 23, and means for simultaneously rotating said feed-rollers in the same direction, the bevel-gear 37 carried by said feed-roller 26 and means for automatically adjusting said bevel-gear 36, longitudinally on its shaft, to compensate for the adjustment of the feed-roller 26, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOSEPH ROLLINS.
